My daughter takes it for complicated migraines that lead to seizures and topomax is an anti seizure
drug. Her neurologist never mentioned hair loss. I even called to verify. She said that hair loss isn't mentioned. but that everyone's system is different. If extreme weight is involved then that is the culprit not the drug. The drug only helps kill the appetite. YOu still need some will. The weight loss you are taking about is fantastic.
